Developing a Hurricane and Storm Damage Risk Reduction System

After the immediate Hurricane Katrina disaster recovery efforts, the U.S. Army Corps of Engineers (USACE) set forth to develop and design New Orleans' $14.5 billion Hurricane and Storm Damage Risk Reduction System (HSDRRS).  This system was designed to provide flood protection up to 100-year levels and is comprised of numerous features including levees, floodwalls, floodgates, surge barriers and pump stations.

Stanley Consultants provided professional program management services to facilitate the design and construction of the HSDRRS.  A team of our professional engineers were embedded within the USACE, Rock Island District staff in a program titled Rock Island New Orleans Support (RINOS).  The RINOS program covered four areas on the New Orleans West Bank and Vicinity:

  • Western Tie-In: Levees, railroad and highway closures, floodwalls, a highway bridge, and a navigable sector gate.
  • Eastern Tie-In: Levees, floodwalls, railroad and highway closures, two stormwater pump stations, and a stoplog closure structure across a navigation canal.
  • Algiers Canal: Levees, floodgates and pump station fronting protection. 
  • The fronting protection included floodwalls, pump discharge tubes, backflow prevention and fender dolphins.
  • West Closure Complex: Largest sector gate (U.S.) and stormwater pump station in the world, floodwalls, sluice gates, levees, roads, fuel tank farm, a water main, a wastewater treatment plant, channel excavation, and fender dolphins.

The construction contract for the West Closure Complex was the first usage of Early Contractor Involvement (ECI) for a USACE Civil Works Project.  ECI enabled early procurement of long-lead items, and enabled collaboration among designers and constructors to develop strategies to deliver the project within budget and schedule.  This collaboration enabled months to be shaved from this $1 billion project, and achieved the June 2011 protection deadline.
